Description

Novel LED lamp with two-section telescopic lamp cup design

Technical Field

The utility model relates to the field of LED light sources, in particular to an improved novel LED lamp with a double-section telescopic lamp cup design.

Background

LED lamps, such as LED spot lamps, are widely used due to their advantages of power saving, safety, high brightness, long life, etc. Among them, the MR16 type LED spotlight is a popular lamp type, and has been widely used worldwide, especially in outdoor courtyard landscape lighting, and the MR16 spotlight has been replaced by LEDs substantially entirely.

The current MR16 spot lamp is based on white light and has sufficient brightness to replace halogen lamps. In outdoor courtyard landscape lighting, a colorful color-changing MR16 is strongly required, preferably an MR16 in which both the color light and the white light can be changed, and the brightness of the color light is enough (the brightness of a single color is up to 6 w). At present, the MR16 with single color R/G/B color change exists in the market, but the power is only about 2w, the brightness is too low, the mixing effect of white light and color light is poor, and color separation often occurs. In order to improve the performance, some manufacturers adopt lengthening lamp cup sizes, and because the sizes exceed the standard, many LED lamps are not matched, so that the market demands are difficult to meet.

The current MR16 shot-light adopts lens + lamp cup + three-section type that connects mostly, and the light source is packed into by the anterior segment, and the power is packed into from the joint end, and this benefit is convenient for light source, power can reprocess respectively, and the utilization ratio of the space in lamp cup is low, can't hold bigger size power in the defect. If an MR16 lamp with sufficient power brightness to dim RGB + white light is to be realized with a physical size that meets IEC standard or ANSI standard, a larger power supply would have to be accommodated. This presents new challenges to existing structural designs.

In view of the foregoing, there is a strong need in the art for improved LED spot lights, and in particular LED lights with innovative antenna improvement designs and arrangements, to overcome or ameliorate the above-described technical deficiencies, and to achieve corresponding and further advantageous technical effects.

The information included in this background section of the specification of the present utility model, including any references cited herein and any descriptions or discussions thereof, is included solely for the purpose of technical reference and is not to be construed as a subject matter that would limit the scope of the present utility model.

First embodiment

Fig. 1 is a schematic front projection view showing the side of a novel LED lamp having a two-segment telescopic (also referred to as a double nested) lamp cup design according to a first embodiment of the present utility model. Fig. 2 is an exploded schematic view of the novel LED lamp shown in fig. 1, schematically illustrating the general construction and assembly of the novel LED lamp. Fig. 3 is a schematic longitudinal sectional view of the novel LED lamp shown in fig. 1, after assembly, along its longitudinal centerline, schematically showing a schematic construction and partial details of the assembly of the novel LED lamp.

As shown in fig. 1-3, a novel LED lamp with a dual segment telescopic lamp cup design is disclosed, comprising a power module 20 and a light source module 10, the power module 20 and the light source module 10 being e.g. detachably or releasably assembled together.

The light source module 10 includes a first generally cylindrical lamp cup section 16, an LED lamp panel 15 mounted within the first cylindrical lamp cup section 16, and an optical lens module 12. The LED lamp panel 15 mainly includes a heat dissipation substrate, a plurality of LEDs preferably packaged on the heat dissipation substrate by COB (Chip on Board), and optionally a plurality of pads. The number, power and color of the LEDs, e.g., colored LEDs and white LEDs, may vary depending on the customer's requirements and design requirements. The heat-dissipating substrate is preferably a substrate that conducts heat well, such as a ceramic substrate and a metal substrate (e.g., an aluminum substrate), in order to provide good heat dissipation properties to the LED lamp. COB packages are preferred for fully utilizing the limited cup volume of LED lamps, good heat dissipation design, and increased optical power. According to an example, in the LED lamp of the present utility model, the LEDs may be single color LEDs, multi-color LEDs, white LEDs, and the light power (brightness) and color, color temperature of the LEDs may be varied, for example, the color temperature of the white LEDs may be adjusted in the range of 2200K-6000K, and may be intelligently adjusted in an intelligent, wireless communication (e.g., bluetooth, as described below) manner.

In order to realize the wireless intelligent regulation function on the novel LED lamp, a Bluetooth antenna is arranged on the novel LED lamp so as to receive (and/or transmit) Bluetooth signals. To this end, according to an example, an antenna bracket 13 may be mounted in the first cylindrical lamp cup section 16 to facilitate assembly of the bluetooth antenna. As shown in fig. 2-3, the antenna support 13 may be integrally formed of, for example, a circular arc segment with supporting legs formed by injection molding plastic, where the supporting legs of the antenna support 13 are supported on the LED lamp panel 15, and the circular arc segment of the antenna support 13 is clamped between the optical lens module 12 and the LED lamp panel 15, specifically, the circular arc segment of the antenna support 13 is propped against the back surface of the optical lens module 12 and forms a clamping groove 18 with the optical lens module 12 (as shown in fig. 3), so that the bluetooth antenna is reliably arranged (e.g., clamped) between the antenna support 13 and the clamping groove 18 formed between the optical lens module 12 and is spaced apart from the first cylindrical lamp cup segment 16 of metal and the LED lamp panel 15 (as shown in fig. 3), so as to avoid being too close to the lamp cup, in order to minimize or eliminate possible metal shielding interference.

According to an example, the maximum light power of the new LED lamp is at least 6 watts, and both the light power and the light color of the new LED lamp are adjustable. For example, the new LED lamp can be operated at full power 6W when operating at any of its light colors, a high light power being desirable and more cost-effective for the user. In contrast, many similar LED lamp products on the market are not enough in power when emitting monochromatic light, even only 30% of the power, namely about 2W, and only near 6W when mixing white light. Therefore, the novel LED lamp provided by the utility model not only can reduce development difficulty, but also can reduce production and use costs.

The power module 20 generally includes a unitary cup-shaped or cup-shaped second cup-shaped cup section 21, an LED drive power supply 17 mounted within the second cup-shaped cup section 21, and an external power connector 22. The second cup-shaped lamp cup section 21 has an open end, i.e. the end connected to the first cylindrical lamp cup section 16; and an opposite convergent end (or "convergent end"), i.e., the end in which the external power connector 22 is mounted, such as by snap-in insertion. As shown in fig. 1, a first cylindrical cup section 16 is removably telescopically assembled to the open end of the second cup section 21 and the outer power connector 22 is connected to the converging end, resulting in an LED lamp having a double nested or telescopic cup configuration as shown in fig. 1 and 3 after assembly. To this end, according to one example, the outer diameter of the first cylindrical lamp cup section 16 is designed to be less than or equal to the inner diameter of the open end of the second cup-shaped lamp cup section 21, and the first cylindrical lamp cup section 16 is detachably assembled in the open end such that the first cylindrical lamp cup section 16 is nearly flush with the open end in the axial direction or slightly exposes the open end (shown in fig. 3).

As shown in fig. 2-3, one example configuration of the removable telescoping assembly is to design external threads 161 in the assembly section of the first cylindrical cup section 16 and 211 in the corresponding assembly location of the second cup section 21, whereby the first cylindrical cup section 16 is removably threaded (screwed) telescoping assembled with the second cup section 21 and can be easily counter-screwed disassembled.

As shown in fig. 2-3, according to an example, the new LED lamp may further comprise an aluminum press ring 11, the aluminum press ring 11 being a tight fit (interference fit) in the circumferential direction between the first cylindrical lamp cup section 16 located radially outward and the optical lens module 12 located radially inward when the new LED lamp is assembled, so as to press the optical lens module 12 against and fix it on the first cylindrical lamp cup section 16. The assembly structure and the assembly mode make full use of the aluminum compression ring which is easy to deform and assemble, and the aluminum compression ring has good heat dissipation, can be convenient and fast, has low cost and is easy to disassemble and maintain, the structure of the LED lamp is simplified, and the most important is that the structural space of the LED lamp is greatly saved. Thus, the lenses of the optical lens module 12, whether concave, convex or planar, can be easily removed and replaced to meet customer and application requirements without having to re-customize the entire LED lamp, thereby greatly saving the cost of producing, designing, installing and maintaining the LED lamp, which is of great benefit to both customers and manufacturers.

To ensure good heat dissipation and lifetime of the LED lamp of the present utility model, according to an example, the first cylindrical lamp cup section 16 and the second cup-shaped lamp cup section 21 may each be formed of a thermally conductive material, e.g. a metallic material such as aluminum, integrally molded. Also, inner heat radiating fins 213 may be provided on the inner peripheral wall of the second cup-shaped lamp cup section 21, and outer heat radiating fins 214 may be provided on the outer peripheral wall thereof so as to promote heat radiation. The inner heat sink fins 213 not only facilitate heat dissipation, but also increase the heat dissipation area, but also facilitate more or less convective heat dissipation of air, due to the axially extending, radially inwardly projecting ribs/ridges or fin configuration of the inner heat sink fins 213 themselves, further creating a radial space between the second cup-shaped lamp cup section 21 and the optical lens module 12 that extends axially for a length.

According to an example, the outer power connector 22 is preferably integrally injection molded with the plastic bracket 220 from two power pins (or pins, etc.) 222 to preserve/increase the power pin metal portion as much as possible, and to increase the heat capacity and heat dissipation area to ensure adequate heat dissipation and durable stability. The power pin 222 has one end exposed to the external power connector 22 and the other end electrically connectable to the LED driving power source 17 through an internal wire (not shown). The plastic bracket 220 is provided with two wedge-shaped reverse buckling parts 221 at the other end opposite to the exposed end of the power pin 222. In this way, during assembly, the external power connector 22 can be inserted from the converging end, so that the wedge-shaped back-off 221 snaps against one step 210 of the second cup-shaped lamp cup segment 21, while the step structure (shown in fig. 3) of the plastic bracket 220 snaps against the other stop step 212 of the second cup-shaped lamp cup segment 21, thereby snapping the external power connector 22 onto the converging end of the second cup-shaped lamp cup segment 21. In the process of disassembly, other internal structures of the second cup-shaped lamp cup section 21 can be disassembled, and the wedge-shaped back-off part 221 is pinched from top to bottom from the second cup-shaped lamp cup section 21 shown in fig. 3 to be separated from the buckle, and is pushed out from the convergence end from top to bottom, so that the disassembly can be completed.

Second embodiment

The general concept and construction of the second embodiment is substantially the same as the first embodiment, except for the design of the antenna and the construction and features associated therewith.

Fig. 4-8 schematically illustrate a new LED lamp with a two-segment telescopic lamp cup design according to a second embodiment of the present utility model. Wherein fig. 4 is an exploded schematic view of a new LED lamp with a two-segment telescopic lamp cup design according to a second embodiment of the present utility model, schematically illustrating the general construction and assembly of the new LED lamp. Fig. 5 is an exploded schematic view of the second embodiment novel LED lamp of fig. 4, taken longitudinally along its longitudinal centerline, at the time of assembly, generally showing the separate first and second cup-shaped lamp cup segments 116 and 121 prior to assembly, and schematically showing a schematic construction and partial details of the assembly of the second embodiment novel LED lamp. Fig. 6 is an exploded schematic view of the assembled novel LED lamp of fig. 5, taken longitudinally along its longitudinal centerline, generally showing the configuration and positional relationship of the assembled first and second cup-shaped lamp cup segments 116 and 121, as well as other schematic components. Fig. 7 shows a groove formed in the top surface of the optical lens module 112 of the new LED lamp of this second embodiment for receiving the foil strip and the antenna. Fig. 8 shows a through hole or through groove formed on the circumferential side wall of the generally truncated conical body of the optical lens module 112 of the novel LED lamp of this second embodiment, through which the antenna passes when assembled, so that the antenna can thereby be mounted to be exposed to the top surface of the optical lens module 112.

As shown in fig. 4-8, a second embodiment of the present utility model is shown of a novel LED lamp also having a two-segment telescopic (also referred to as a double nested) lamp cup design. The LED lamp includes a power supply module 120 and a light source module 110, and the power supply module 120 and the light source module 110 are, for example, detachably or releasably assembled together. The light source module 110 includes a first generally cylindrical lamp cup section (which also acts as a heat sink) 116, an LED lamp panel 115 mounted within the first cylindrical lamp cup section 116, and an optical lens module 112. The COB package has an LED light source on the LED lamp panel 115.

The power module 120 generally includes a second cup-shaped cup section 121 that is integrally cup-shaped or cup-shaped, an LED drive power supply 117 mounted within the second cup-shaped cup section 121, and an external power connection 122. The second cup-shaped lamp cup section 121 has an open end, i.e. the end connected to the first cylindrical lamp cup section 116; and an opposite converging end (or "necked-in end"), i.e., the end in which the external power connector 122 is mounted, such as by snap-in insertion. As shown in fig. 1, a first cylindrical cup section 116 is removably telescopically assembled at the open end of the second cup section 121, and the outer power connector 122 is connected at the converging end, resulting in an LED lamp having a double nested or telescopic cup configuration after assembly is completed. To this end, the outer diameter of the first cylindrical lamp cup section 116 may be designed to be less than or equal to the inner diameter of the open end of the second cup-shaped lamp cup section 121, and the first cylindrical lamp cup section 116 may be removably assembled in the open end such that the first cylindrical lamp cup section 116 is axially nearly flush with the open end or slightly exposes the open end (shown in fig. 5-6).

As shown, one example configuration of removable telescopic assembly is that the first cylindrical lamp cup section 116 is telescopically assembled with the second cup-shaped lamp cup section 121 and removably secured together by screws 114 (e.g., two screws 114 as shown in fig. 4-5). The detachable design by screw fixation of the present embodiment makes it possible to make the contact between the two heat sinks 116 and 121 as close as possible and the contact surface as large as possible, compared with the screw-fit design in the first embodiment, whereby heat dissipation can be improved.

As shown in fig. 4-6, according to an example, the novel LED lamp may further comprise an aluminum press ring 111, the aluminum press ring 111 being tightly fitted (interference fit) in the circumferential direction between the first cylindrical lamp cup section 116 located radially outward and the optical lens module 112 located radially inward when the novel LED lamp is assembled, so that the optical lens module 112 is fixed by being pressed against and fixed to the first cylindrical lamp cup section 116. The assembly structure and the assembly mode make full use of the aluminum compression ring which is easy to deform and assemble, and the aluminum compression ring has good heat dissipation, can be convenient and fast, has low cost and is easy to disassemble and maintain, the structure of the LED lamp is simplified, and the most important is that the structural space of the LED lamp is greatly saved. Therefore, the lens of the optical lens module 112, whether it is a concave lens, a convex lens or a planar lens, can be easily disassembled and replaced to meet the requirements of customers and applications without the need of re-customizing the entire LED lamp, thereby greatly saving the production, design, installation and maintenance costs of the LED lamp.

The first cylindrical lamp cup section 116 and the second cup-shaped lamp cup section 121 may each be formed of a thermally conductive material, for example, a metallic material such as aluminum, integrally molded. Also, inner heat radiating fins 213' may be provided on the inner peripheral wall of the second cup-shaped lamp cup section 121, and outer heat radiating fins 214 may be provided on the outer peripheral wall thereof so as to promote heat radiation. The inner heat sink fins 213 'not only facilitate heat dissipation, but also facilitate convective heat dissipation of air due to the axially extending, radially inwardly projecting ribs/ridges or fin configuration of the inner heat sink fins 213' themselves, further forming a radial space between the second cup-shaped lamp cup section 121 and the optical lens module 112 that extends axially a length.

According to an example, the outer power connector 122 is preferably integrally injection molded with the plastic carrier 220 'from two power pins 222' to preserve/increase the power pin metal portion as much as possible, increasing the heat capacity and heat dissipation area to ensure adequate heat dissipation and durable stability. The power pin 222' has one end exposed to the external power connector 122 and the other end electrically connectable to the LED driving power source 117 through an internal wire (not shown). The plastic bracket 220' is provided with two wedge-shaped reverse buckling parts 221' at the other end opposite to the exposed end of the power pin 222 '. Thus, see, for example, the structure and illustration of the first embodiment: upon assembly, the outer power connector 122 may be inserted from the converging end such that the wedge-shaped undercut 221 'snaps against a step of the second cup-shaped cup segment 121 to secure, while the stepped structure of the plastic bracket 220' snaps against another stop step of the second cup-shaped cup segment 121. Thereby, the outer power connector 122 is snapped onto the converging end of the second cup-shaped lamp cup section 121; when the second cup-shaped lamp cup section 121 is detached, other internal structures of the second cup-shaped lamp cup section 121 can be detached, the wedge-shaped back-off part 221' is pinched from top to bottom from the second cup-shaped lamp cup section 121 to be separated from the buckle, and the wedge-shaped back-off part is pushed out from the convergence end from top to bottom, so that the detachment can be completed.

The main difference between this second embodiment and the first embodiment is that the antenna design and associated features of the first embodiment are replaced by the antenna design and associated features shown in fig. 4-8. In the design of the new LED lamp of the first embodiment, particularly with a first and a second metal cup section (in general, a cup section of metal such as aluminum is used for improved heat dissipation), the wireless communication signal transmitted to the antenna of the LED lamp will be shielded to a certain extent by the metal cup due to the well known "electromagnetic shielding" effect of the metal shell, so that the signal received by the antenna arranged in the first embodiment is relatively weak and the effective signal transmission (wireless control) distance is short. Therefore, through the design of the present inventor and multiple verification tests, the design in the second embodiment is adopted, and the antenna 113B is configured and arranged to be far away from the metal lamp cup (housing) as far as possible, for example, to be exposed to the surface of the LED lamp (such as the surface exposed to the light emitted by the optical lens, for example, the top surface of the lens, or a top surface above the light emitting surface of the lens), so that the problems of electromagnetic shielding and weak received signal of the antenna design in the first embodiment can be alleviated, thus obtaining a relatively ideal longer signal transmission (wireless control) distance, greatly improving signal control, and not affecting the emitted beam pattern (light spot).

To this end, as shown in fig. 5 to 8, a strip-shaped metal antenna 113B, for example, a wire-shaped or thin strip-shaped, is mounted and fixed in the LED lamp, for example, in the second metal cup section 121, connected and fixed to a circuit board where the LED driving power source 117 is located, passes upward through the LED lamp panel 115 and through a through hole or through groove 112B on the circumferential side wall of the generally truncated cone-shaped cup body of the optical lens module 112, is folded, is embedded in a card slot 112A formed in the top surface of the optical lens module 112 in a manner generally parallel to the top surface (i.e., the top surface on the light exit side) of the optical lens module 112, and is snap-fixed in the card slot 112A by a strip-shaped bead 113A, for example, preferably, the bead 113A is generally flush with the top surface after the antenna 113B is mounted, for the sake of aesthetic appearance and convenience and reliability of the subsequent mounting of the LED lamp. According to one example, after assembly is completed, the antenna 113B is secured within the card slot 112A, whereby the antenna 113B is mounted substantially flush from the top surface of the LED lamp light lens module 112 and away from the metal cup, greatly improving the problem of relatively weak antenna control signals. The grooves may be, for example, grooves extending along the diameter of the circumference of the top surface, not only for aesthetic reasons, but also to minimize the effect on the light output and spot pattern of the lens. Antenna 113B may preferably extend substantially the entire length of card slot 112A to maximize signal reception. Also, one example of the bead 113A may be selected to be metallic, such that the bead 113A is in metallic connection with the antenna 113B and in effect acts as an enlarged portion of the antenna 113B, further improving signal reception and signal shielding issues.

According to one example, in the inventors' actual measurement test, the effective wireless control distance of the novel LED lamp of the first embodiment is only about 2-3 meters, whereas the effective wireless control distance of the novel LED lamp of the second embodiment may be as high as at least 10 meters or more.

According to an example, the novel LED lamp of the present utility model is primarily designed as an MR16 type LED lamp, such as an LED spotlight, primarily for outdoor courtyard landscape lighting. Thus, according to a preferred example, the novel LED lamp of the present utility model is designed such that its total length (or total height of the lamp) and the maximum outer diameter of the lamp cup (i.e. the maximum outer diameters of the second cup-shaped lamp cup section 21 and the second cup-shaped lamp cup section 121 shown in fig. 2-3 and fig. 4-6) meet the requirements of the IEC60630-4010-2 standard in order to meet the requirements of customers and markets. The overall length and maximum outer diameter of the lamp cup of the new LED lamp of another example of the present utility model may also be designed to conform to the american national standard ANSI-C78.24-2001 to meet and facilitate the demands of the united states market and users.

As described above, the novel LED lamp of the present utility model can wirelessly regulate and control the light power/brightness by wireless communication, such as bluetooth communication, including regulating and controlling the light power/brightness of the LED lamp by MCU or by resistor, etc. The regulation and control of the light power/brightness of the LED lamp by the MCU is a preferable scheme, because different electric signals can be output by using a preset control program in the MCU to control the output current, thereby greatly reducing the design volume of the circuit board and the LED lamp, which is very ideal and valuable for the LED lamp meeting the requirements of relevant foreign standards.

The novel LED lamp is suitable for being used as various LED spot lamps, such as outdoor LED spot lamps, especially high-power outdoor LED spot lamps, courtyard LED spot lamps, landscape lighting LED spot lamps and the like.

The foregoing description of several embodiments of the utility model has been presented for the purposes of illustration. It is not intended to be exhaustive or to limit the utility model to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The scope of the utility model and all equivalents are intended to be defined by the appended claims.
